1 · What the graph read from it

What it found

Each row is one number read from the abstract, on the scale the paper reported it, with its interval. Left of the dashed line favours the treatment, right favours the comparator. Under each row is the sentence it came from. New to these charts? A ten-minute tutorial.

The abstract states no effect estimate the extractor could read, or names no intervention and outcome on the map, so this paper lights no cell and moves no belief. It is still indexed, cited and linked below.

2 · The registry

The trial behind it

Trials whose registry record cites this paper, or whose number appears in the abstract. A trial that started after this paper was published is citing it as background, not reporting it.

Neither the registry nor the abstract names a trial number. If this is a trial report, that itself is worth knowing.

Abstract

purposeCytochrome P450 1A1 (CYP1A1) polymorphisms were implicated in endometriosis risk, but individual published studies showed inconclusive results. Thus, a meta-analysis was performed to clarify the effect of CYP1A1 polymorphisms on endometriosis risk.

methodsPubMed, Embase, and CNKI databases were searched to identify the eligible studies focusing on the associations between CYP1A1 MspI and Ile462Val polymorphisms and susceptibility to endometriosis. Summary odds ratios (ORs) and 95 % confidence intervals (95 % CIs) for CYP1A1 polymorphisms and endometriosis were calculated.

resultsPooled analysis of 12 studies involved a total of 1555 cases and 2868 controls showed that in all genetic models, no significant association between CYP1A1 MspI polymorphism and endometriosis risk was observed in the overall, Asians and Caucasians population, respectively. Interestingly, increased endometriosis risk was associated with carrying the C allele of CYP1A1 combined with GSTM1 null genotypes. For CYP1A1 Ile462Val polymorphism, eight studies were available (878 cases and 1991 controls). In the overall analysis, CYP1A1 Ile462Val polymorphism had a statistically significant association with increased endometriosis risk in allele contrast and all genetic models except the model of Val/Ile vs. Ile/Ile. In the subgroup analysis by ethnicity, significant elevated endometriosis risk was associated with CYP1A1 Ile462Val polymorphism in Asians but not in Caucasians under all genetic models. No publication bias was found in the present studies.

conclusionsThis meta-analysis suggested that CYP1A1 Ile462Val polymorphism was associated with an increased risk of endometriosis, particularly in Asians. CYP1A1 MspI polymorphism may not be associated with endometriosis risk, but GSTM1 and CYP1A1 MspI polymorphism may have a joint effect on endometriosis risk.
